The 2·95 Ga Pilbara high-Mg diorite suite intrudes the central part of Archaean granite–greenstone terrain Craton, Western Australia, and shows many features typical (sanukitoid) suites from other late terrains. Such form a minor component felsic crust. They are typically emplaced in late- to post-kinematic settings, sometimes association with alkaline magmatism, either unaccompanied by, or post-date, tonalite–trondhjemite–granodiorite (TTG) which comprises much greater proportion TTG series...
Abstract The Archean Pilbara Craton contains five geologically distinct terranes – the East Pilbara, Karratha, Sholl, Regal and Kurrana Terranes all of which are unconformably overlain by 3.02‐ to 2.93‐Ga De Grey Superbasin. 3.53–3.17 Ga Terrane (EP) represents ancient nucleus craton that formed through three mantle plume events at 3.53–3.43, 3.35–3.29 3.27–3.24 Ga. Each event resulted in eruption thick dominantly basaltic volcanic successions on older crust 3.72 Ga, melting generate first...
Results from a multidisciplinary geoscience program since 1994 are summarized for the North Pilbara terrain of Craton. Major findings include recognition three separate terranes with unique stratigraphy, geochronological, and structural histories; ca. 3.72 to 2.85 Ga East granite-greenstone terrane, 3.27 2.92 West <3.29 Kuranna terrane in southeast. These separated by two late, dominantly clastic sedimentary basins deposited within tectonically active zones; 3.01 2.93 Mallina basin west...
The Musgrave Province lies at the convergence of major structural trends formed during Proterozoic amalgamation North, West and South Australian Cratons prior to c. 1290 Ma. Orogeny, one three Mesoproterozoic orogenies affect province, produced granites Pitjantjatjara Supersuite, which dominate outcrop. This orogeny was an intracontinental dominantly extensional event in ultrahigh-temperature (UHT) conditions persisted from 1220 1120 onset UHT is heralded by a change low-Yb voluminous...
Abstract How and when continents grew plate tectonics started on Earth remain poorly constrained. Most researchers apply the modern tectonic paradigm to problems of ancient crustal formation, but these are unsatisfactory because diagnostic criteria actualistic configurations lacking. Here, we show that 3.5–3.2 Ga continental nuclei in Pilbara Craton, Australia, eastern Kaapvaal southern Africa, formed as thick volcanic plateaux built a substrate older lithosphere did not accrete through...
Abstract Much of the present-day volume Earth’s continental crust had formed by end Archean Eon, 2.5 billion years ago, through conversion basaltic (mafic) into sodic granite tonalite, trondhjemite and granodiorite (TTG) composition. Distinctive chemical signatures in a small proportion these rocks, so-called high-pressure TTG, are interpreted to indicate partial melting hydrated at pressures above 1.5 GPa (>50 km depth), typically not reached post-Archean crust. These interpretations...
